Windows 100% Disk usage is a more common problem than you’d think… albeit Windows 10 being a new operating system it isn’t flawless nor faultless in it’s design or structure and in fact is susceptible to a few unknown annoyances. These may have been inherited from a previous Windows 7 or Windows 8 installation however if you updated your Windows directly this may’ve contributed to the cause. Although it’s not 100% certain why this happens of why Microsoft hasn’t addressed the issue to date (14th September 2015) the cause of this and making sure it’s minified.
Regardless you may be wondering what the cause of this is, in fact it tends to be the “Microsoft Search” Service running 100% although it shows up in Task Manager as “System”.
- To disable this, use the Windows Search bar and type “Services”, open the Services application.
- Once you’re in the Services Application you may wish to press ‘W’, this will then take you to the point in which all services beginning with W begin with.
- Find the Service named “Windows Search” and right click and select ‘Stop’.
- If you then proceed to open Task Manager (available by the search or Ctrl + Alt + Del)
- Select the ‘Startup’ tab and select ‘Services’ while then proceeding to find Windows Search again, un-tick the selection to make sure that it doesn’t start again on Windows 10 start-up.
This will then take effect immediately and the service should cease while also starting to decrease in I/O (Disk) usage almost if not immediately. It seems to be that the whole process is designed to index different aspects of your operating system and make windows search faster however I’ve noticed that it makes no real noticeable difference and the search function still works – so needn’t worry!
This amendment won’t cause any damage to your Windows 10 (or 7 & 8) installation and shall keep your Windows functioning in a healthier state if you’re experiencing this issue. You’re able to re-enable the steps above by doing them in the same order however re-enabling or ‘starting’ the service.
